Some books kill. This one wants you alive.

James Trondheim—nicknamed The Femme Fatale Killer—is days from lethal injection for a murder he didn’t commit. The world thinks he butchered rising political star Jennifer Falin. The truth? Something far stranger slipped into his life the night she died: an ancient, leather-bound book that whispers between its pages.

Moments before his execution, strangers pull him from death’s grip. They know what the book is. They know what he is. And they’re not saving him out of kindness.

Dragged into a maze of secret estates, impossible staircases, and a library that rewrites reality itself, James discovers the book, The Arcanum Infernum, isn’t finished with him. It likes him. That might be the most dangerous thing about it.

Witchbook is a razor-edged supernatural thriller for fans of Paul Tremblay, Alex North, and Stephen King’s darkest worlds—where creeping dread bleeds into shifting realities, and the story you’re reading might already be reading you back.
